Answer 1

Answer:

x ≈ 50.8

Step-by-step explanation:

Given

sin80° = $\frac{50}{x}$

Multiply both sides by x

x × sin80° = 50 ( divide both sides by sin80° )

x = $\frac{50}{sin80}$ ≈ 50.8 ( to 1 dec. place )

Answer 2

Answer:

$\large\boxed{x\approx50.77}$

Step-by-step explanation:

$\text{Look at the picture.}\\\\\sin80^o\approx0.9848\\\\\text{Substitute it the the equation}\ \sin80^o=\dfrac{50}{x}:\\\\0.9848=\dfrac{50}{x}\\\\\dfrac{9848}{10000}=\dfrac{50}{x}\qquad\text{cross multiply}\\\\9848x=(10000)(50)\\\\9848x=500000\qquad\text{divide both sides by 9848}\\\\x\approx50.77$
